"""v66 -- the compiler atoms ARE the E8 Casimir invariant degrees.

An organizing simplification (not a new input): the load-bearing integers of the
compiler coincide with the fundamental invariant degrees of E8,
    deg(E8) = {2, 8, 12, 14, 18, 20, 24, 30}   (exponents + 1).
Since E8 is the audit hull, its invariant degrees being the theory's integers is
structurally EXPECTED -- a consistency check confirming the E8 choice, not a coincidence.

Honest clean/fittable split:
  CLEAN/non-trivial : 2=|Z2|, 8=rank E8, 14=dim G2 (the K/Q commutator G2, v37),
                      20=det L (v10), 24=|W(A3)|=4!, 30=h(E8)=2*3*5.
  weaker/fittable   : 12=|R(A3)|, 18=p4(a)=2+2^4.
Exact sum identities:
  sum(degrees)   = 128 = 2^7   (the de Sitter prefactor S_dS=e^{2 ainv}/(128 c3^4);
                               7 = scalaron exponent g+n-1)            [NEW, clean]
  sum(exponents) = 120 = |R^+(E8)| (positive roots, v56)
  prod(degrees)  = |W(E8)| = 696729600 (Weyl group order)
